## Long description

The Mahr MarCal 18EWR is a high-precision digital caliper designed for demanding industrial measurement tasks. With a measuring range of 500mm (20 inches), this instrument provides reliable accuracy for both internal and external dimensions. The device features a robust construction and is equipped with 150mm two-sided jaws, making it versatile for various complex geometries. Its integrated digital display ensures clear readability, while the inclusion of a data output interface allows for seamless integration into quality management systems and digital documentation workflows.
Advantages
This digital caliper stands out due to its IP65 protection rating, which ensures the internal electronics are shielded against dust ingress and water jets, making it highly durable in workshop environments. The high-contrast display provides precise readings, reducing the risk of human error during measurement. Furthermore, the two-sided jaws offer exceptional flexibility, allowing the user to measure deep internal grooves or external features with ease. The integrated data output capability simplifies the process of recording measurements, which is essential for maintaining consistent quality control standards in manufacturing.
Suitable for
Precision measurement of large workpieces in manufacturing
Quality control inspections in industrial settings
Measuring internal and external dimensions with deep reach
Documenting measurement data for compliance and reporting
When it may not be suitable
This caliper may not be the ideal choice for extremely small-scale precision work where a shorter range or specialized micro-measuring tools are required. Additionally, if your application involves complete submersion in liquids, the IP65 rating is insufficient, and a tool with a higher ingress protection rating should be selected.

How to use
To use the Mahr MarCal 18EWR, ensure the measuring surfaces are clean and free of debris. Power on the device and perform a zero-setting by closing the jaws completely and pressing the zero button.

Verify that the 500mm range is sufficient for your largest workpieces
Ensure your data collection system is compatible with the Mahr data output interface
